why? well very easy my dude =).
100 xp from ur hero + a spot creped just after to maximize the advantage he has over you will give him a lvl 2 (half way to lvl 3 hero.).
Don't tell me he will wait in his base after he killed ur hero and mass units, waiting for ur hero to revive and then.. let u creep and eventually after that he also goes creeping also.
I give u an example
..
TM.. u got killed he is human. he gets 3-4 militia + am + w.e + some foots and creeps the 2 lvl 3 gnoll and lvl 5 one next to his base. (if not even either the goblin shop or the merc camp which will make him lvl 3)
Also orcs can very easily take that spot with 2 grunts and a FS.
I can assure u he will have lvl 2 and half after
. While this time all u got to do is.. revive ur hero and eventually replenish ur mana.
TP or die? your pick on how badly u wanna lose or win the game
.
